What is 7X plus 8?
The expression 7X + 8 represents a mathematical operation where the variable X is multiplied by 7 and then 8 is added to the result. The expression cannot be simplified further without knowing the specific value of X. If X is a known value, you can substitute it into the expression to find the numerical result.
What is 2x plus 5?
Well, darling, 2x plus 5 is just an algebraic expression that represents the sum of 2 times a variable x and 5. So, if you want to find the value of that expression, you need to know the value of x. Math can be a real hoot sometimes, can't it?
How do you Solve x2-5x-36 equals 0?
x2 - 5x - 36 = 0 (x - 9) (x + 4) = 0 x = 9 and x = -4 This method is called factoring and only works if the equation is a perfect square otherwise you must use the quadratic equation. There are not enough mathematical symbols here to illustrate so you'll have to look it up. But you can determine if the equation is factorable using a part of the quadratic equation called the discriminate, if the discriminate is a perfect square the equation is factorable. b2 - 4ac (discriminate) Where a,b, and c are taken from the general form ax2 + bx + c = 0 a = 1, b = -5, c = -36 If the square root of the discriminate is a whole number 3, 8, 122... the equation is factorable. Notice above that 9 x -4 = -36 the c value and 9 + (- 4) = 5 the b value. Start solving by listing all multiples of -36 and choose the two which when added give you 5.
